sys-process/nohang::bentoo
- Ebuilds: 2, Testing: 0.3.0, Snapshot: 9999 Description:
Userspace low memory handler. It watches PSI (Pressure Stall Information)
-- the kernel's measure of how long tasks actually stall waiting on
memory -- along with MemAvailable and swap, and terminates the heaviest
offender before the machine starts thrashing. The kernel OOM killer only
acts once an allocation has already failed, by which point the desktop
has typically been unresponsive for minutes.
It is the closest equivalent to systemd-oomd for hosts that do not run
systemd: systemd-oomd is also PSI-driven, but ships as a systemd unit and
kills whole cgroups, whereas nohang is init-agnostic and picks individual
processes through a configurable badness score. Unlike sys-apps/earlyoom
it reads PSI rather than free-memory percentages alone.
Two configuration profiles are installed and they are mutually exclusive:
nohang for headless and conservative setups, nohang-desktop for
interactive machines, which additionally warns the logged-in user through
desktop notifications before anything is killed.

sys-process/parallel::bentoo
- Ebuilds: 1, Testing: 20261022 Description:
GNU parallel is a shell tool for executing jobs in parallel locally or
using remote machines. A job is typically a single command or a small
script that has to be run for each of the lines in the input. The
typical input is a list of files, a list of hosts, a list of users, a
list of URLs, or a list of tables.
If you use xargs today you will find GNU parallel very easy to use as
GNU parallel is written to have the same options as xargs. If you
write loops in shell, you will find GNU parallel may be able to
replace most of the loops and make them run faster by running several
jobs in parallel. If you use ppss or pexec you will find GNU parallel
will often make the command easier to read.
